Chemical Basis Of Life Flashcards
(20 cards)
Three physical states of matter
Solids, liquids, and gases
Water is a _ molecule
Polar
Four types of organic compounds important in biochemistry
Carbohydrates, lipids, proteins, and nucleic acids
Organic molecules, fatty acids, fats, phospholipids, steroids, and prostaglandins
Lipids
Mono and poly
One & many
Characteristics of bases
They bind hydrogen ions and they release hydroxide ions
The PRODUCTS of a chemical reaction
Produced by the chemical reaction
Molecules that attract water or dissolve in it because of their polar nature
Hydrophilic “forms the head”
Simplest form of matter
Element
Three functions of proteins
Catalyze chemical reactions, carries substances within the blood, and function as receptors on cells’ surfaces
Nucleotide consists of a phosphate group, a nitrogen-containing organic base, and a 5-carbon
Sugar
Carbohydrate formed from two single sugars bonded together
Disaccharide
Function of water
A major component of blood; water transports various dissolved substances throughout the body
Molecules that influence the rate of chemical reactions without being changed themselves
Catalyst
Examples of lipid compounds
Fats, triglycerides, and steroids
Four ions that are important to the functioning of the body
Calcium, chloride, sodium, and potassium
Two or more atoms that bond together form an
Molecule
Compounds are classified as acids if they release _ when they dissociate in water
Hydrogen ions
Describe an ionic bond
Binds a cation to an anion
Chemical reactions are said to be _ if they can proceed in either direction
Reversible
